IMPROVEMENT IN SPRING BED-BIOTTOMS.. I

The- Schedule referred to in these Letters Patent and making part of thesaule.

To all whom it may concern.:

Be vknown that I, JOSEPH E. LORD, of the city of Quincy, in the countyofAdams and State of lllinois, have invented certain new and usefulImprovements in Spring Bed-Bottoms, of which the following is aspecication, reference being had to the accolnpanying drawing.

l Nature and Objects of the Invention.

The invention relates tovthatclass of metal-spring bed-bottomsconsisting of lattice or basket-work top and bottom-frames, having metalsprings between and connecting the same. f v

The object ot' the .invention is to prevent the dis-l GeneralDescription.

A in the accompanying drawing represents the longitudinal slats orstraps, which are secured at each end to the upper surface of the frameO. The slats next the frame on each sidepass under, and the remainingslats alternately over and under the' alternate transverse slats orstraps B. A

By this arrangement the slats are prevented from separating, thestructure of the frame is rendered more compact, and mutual support andelasticity given to all the slats thereof.

'lhe lower frame is similarly constructed to the up- The springs D, o fcommon pattern, connect the np per and lower frames, and are secured inthe following manner .to the slats thereof:

1n the first row of springs on each side, the upper curve of the springrises from below the longitudinal slat on the upper frame, passes overthe adjacent transverse slat near its junction with t-he rim or frame C,thence under the longitudinal slat, and tinally above the transverseslat, in which, at a. proper dis-v tance from the said longitudinalslat, an aperture is provided, through which the eudbf the materialcomposing the spring is passed and clamped or otherwise secured on theunder side of the slat, the vertical center of the spring being directlyunder the point where the slats cross.

vThe springs at each end of the bed-bottom are simr ilarly arranged,save that they are secured to the longitudinal slats.'

The springs in` the rows between the end and side rows of springs aresecured alternately in the transverse and longitudinalslats, from sideto side. When in the former, the upper curve ofthe spring rises frombelow the longitudinal slat, 'passes over the adjacent transverse slat,thence on the opposite side under the longitudinal slat, and is finallysecured as aforesaid.

When in the latter, the arrangement of the spring is 'vico corsa.

The springs aresecnred in thesame manner to both upperand'lower't'rames.l

In thesaid patent the bed-bottom consists of slats, the longitudinalones being laid upon and over the transverse, the former being securedto one and the .latter to the other side of the rim or frame (l. Also,

in said spring bed-bottom the springs are all secured to the transverseslats.

My improvement consists herein- First, the arrangement of the slats,alternately passing over and under alternate slats.`

Second, in the method of securing the springs alternately to thelongitudinal and transverse slats.

The upper and lower surfaces of the bed-bottom, the inner portions ofthe frames, as well as the springs, are thoroughly `cam-'ered withcopal, shellac, or other hard-faced varnish, to prevent the ticking ofthe snperposed mattress or bed adhering to the bed-bottom, toprevent-the same from rust, and to seal the apertures therein againstvermin. V r

Claim.

109,445, and dated November 22, 1870; but

AWhat I do claimas my invention, and desire to secure by Let-tersPatent, is- A The arrangement ot' the longitudinabslats-A and thetransverse slats B, supported at their ends by and secured to theexterior surface of the frames C and passing alternately over and undereach other-this arrangement in combination with the arrangement 0i' thesprings D, secured at each extremity by passing it through an aperturein and clamping it to the under side of alternate longitudinal andtransverse slats, substantially as shown and described.

In testiony that I claim the foregoing improvements `in springbed-bottoms I have hereuntoset my hand and seal this 3d day ot' January,1871.
